Need a reminder of how fleeting our celebrity gossip obsessions tend to be? South Park (Comedy Central, tonight, 9:30 ET/PT) repeats the 2003 episode that viciously mocked all the fuss over the not-to-be marriage between Jennifer Lopez and Ben Affleck. You remember, right?

Tom Cruise as Col. Claus von Stauffenberg, a real-life aristocratic German who led a plot to assassinate Hitler, is worlds away from his All-American Top Gun beginnings. Which just may be the point of Valkyrie, the summer 2008 thriller that reunites director Bryan Singer and writer Chris McQuarrie of 1995 film The Usual Suspects.

Drew Carey takes over The Price Is Right (CBS, 11 a.m. ET/10 PT) today, and the host seems right as well. Some nerves show at first, but Carey's good-humored generosity as a performer soon comes to the fore. He has always enjoyed games remember those spot-the-error episodes of The Drew Carey Show? and here he seems so pleased by the game going on around him that there's a good chance Price fans will be equally pleased.

Drew Carey spent his entire career preparing to be a game-show host, only he didn't know it. It wasn't until the 49-year-old comedian became the new face of "The Price Is Right" that he realized game shows were his true calling. Carey makes his "Price" debut on Monday.
